[PATCH v3 0/5] KVM: PPC: Book3e: AltiVec support

Add KVM Book3e AltiVec support and enable e6500 core. Changes: v3: - use distinct SPE/AltiVec exception handlers - make ONE_REG AltiVec support powerpc generic - add ONE_REG IVORs support v2: - integrate Paul's FP/VMX/VSX changes that landed in kvm-ppc-queue in January and take into accou

[PATCH v3 2/5] KVM: PPC: Book3e: Add AltiVec support

Add KVM Book3e AltiVec support. KVM Book3e FPU support gracefully reuse host infrastructure so follow the same approach for AltiVec. Keep SPE/AltiVec exception handlers distinct using CONFIG_KVM_E500V2. Signed-off-by: Mihai Caraman --- v3: - use distinct SPE/AltiVec exception handlers v2: - i

[PATCH v3 3/5] KVM: PPC: Move ONE_REG AltiVec support to powerpc

Make ONE_REG AltiVec support common across server and embedded implementations moving kvm_vcpu_ioctl_get_one_reg() and kvm_vcpu_ioctl_set_one_reg() functions to powerpc layer. Signed-off-by: Mihai Caraman --- v3: - make ONE_REG AltiVec support powerpc generic v2: - add comment describing VCSR

[PATCH v3 1/5] KVM: PPC: Book3e: Increase FPU laziness

Increase FPU laziness by calling kvmppc_load_guest_fp() just before returning to guest instead of each sched in. Without this improvement an interrupt may also claim floting point corrupting guest state. Signed-off-by: Mihai Caraman --- v3: - no changes v2: - remove fpu_active - add descripti

[PATCH 0/7 v3] Guest debug emulation

This patchset adds debug register and interrupt emulation support for guest, which enables running gdb/kgdb etc in guest. v2->v3 - Added One-reg interface for DBSR - removed arch->shadow_dbg_reg - Addressed some more comments on v2 (detail in individual patch) Bharat Bhushan (7): KVM: PPC: B

[PATCH 1/7 v3] KVM: PPC: BOOKE: allow debug interrupt at "debug level"

Debug interrupt can be either "critical level" or "debug level". There are separate set of save/restore registers used for different level. Example: DSRR0/DSRR1 are used for "debug level" and CSRR0/CSRR1 are used for critical level debug interrupt. Using CPU_FTR_DEBUG_LVL_EXC to decide which inter

[PATCH 3/7 v3] KVM: PPC: BOOKE: Allow guest to change MSR_DE

This patch changes the default behavior of MSRP_DEP, that is guest is not allowed to change the MSR_DE, to guest can change MSR_DE. When userspace is debugging guest then it override the default behavior and set MSRP_DEP. This stops guest to change MSR_DE when userspace is debugging guest. Signed-

[PATCH 4/7 v3] KVM: PPC: BOOKE: Clear guest dbsr in userspace exit KVM_EXIT_DEBUG

Dbsr is not visible to userspace and we do not think any need to expose this to userspace because: Userspace cannot inject debug interrupt to guest (as this does not know guest ability to handle debug interrupt), so userspace will always clear DBSR. Now if userspace has to always clear DBSR

[PATCH 7/7 v3] KVM: PPC: BOOKE: Emulate debug registers and exception

This patch emulates debug registers and debug exception to support guest using debug resource. This enables running gdb/kgdb etc in guest. On BOOKE architecture we cannot share debug resources between QEMU and guest because: When QEMU is using debug resources then debug exception must be a

Guest visible debug register and hardware visible debug registers are same, so ther is no need to have arch->shadow_dbg_reg, instead use arch->dbg_reg. Signed-off-by: Bharat Bhushan --- v2->v3 - New Patch ( As per comment we are now using arch->dbg_reg only) arch/powerpc/include/asm/kvm_host.h
